SPECIFICATION forming part of Letters Patent No. 3563174, dated February 1,

Application lled February S, 188B. Serial No. 191,143. (No model.)

' To LZZ whom i' may concern.-

Be it known. that I, JOSEPH S. Miron, a. citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented a new and useful linprovcrnent in Potters Molds, of which the following is a specification.

It relates to n more complete method of manufacturing that class of potters vessels provided either with handles or ears, to either class of which it is equally well adapted, the modos opemfmli being the same in both cases, the substitution of a mold of proper form to make either the enr or the handle, as may be desired, being all the change necessary to make in either case. l

It is on improvement on my pending,N application for improved potters case,H Serial No. 172,24?, led July 21,1885. lts object is to provide a means whereby the handle or ear andthe body of apotters vessel can be formed at a simultaneous operation, and a more perfeet union of the tn'o established by mutual junction while the plastic clay is at its best working temperature and in much less time than is consumed lin putting on the handles at a subsequent operation by the old method.

It consists in a process of handpressing, jig-v gering, and uniting the parts of potters vessels by a conti nuous operation in the saine mold. I accomplish this object by means of the device illustrated in the accompanying dran-- ings, wherein- Figure l represents a. central vertical lon gitudinal section of a mold embodying my im proveinent. lt is fitted in true Working po siticn to my improved potters case, for which the application before alluded to is now pending. Fig. 2 is o horizontal section of the saine, taken on the line o; y.

Lilie letters denote like parts throughout the several Views.

C, Fig. l, representsthcinclosing-case of my combined potter-s cose.

Bis the niold-bottoin forming part of the same.

M M ore senii-cylinders, their outer circumference slightly tapered and fitting snugly in case C. Upon their abutting edges are formed half-molds H H, for rocking 'the handles of pitchers, in combination with which the divided mold M ill forms the body of the pitcher at the saine operation with the handle, each semi-cylinder M M being formed to match the other and containing the other half of the bodymcld and also corresponding half of handlemold, so that when these tivo half-molds, doweled together, are dropped into case G they form e complete and harmonious whole mold, in which the pitcher and handle areY formed simultaneously.

N is a recess formed in joint of molds M M, in which the external shape of the pitchermouth is formed. Its internal shape is subseqnently scooped out by a cutter of corresponding forni.

Having now explained the construction of my improved device, its operation is substantially as follows: A head coinciding with the external surface of case Gis screwed onto a. jiggenspindle, the case C is then dropped into this head, a pull-down lever is adjusted in proper Working position, and a sweep coinciding with the internal shape ofthe desired vessel properly attached to the same. A boy standing on the righthand of the operator ents from a length of clay of proper forni a piece sufcient to make one handle. This he thrusts into the half-mold H, places the other halfmold upon it, sqneezes the two together to a close joint, the waste escaping in a channel scalloped out around the edge of hnndlernold H to receive it. The mold is passed to the operator, who drops it into cose C, drops in a bat of clay, puts jigger-spindle in motion, brings down the sweep on pull-down lever, and almost instantaneously strikes up o. complete potters vessel with handle attached. This mold is now taken to the hot room, another one inserted, and the operation repeated, and so on ed infinitum.

What I claim as myinvention, and desire to secure by Letters Patent, is-

The process of forming the handles of potters7 vessels,which consists of hand-pressing the plastic clay between the two halves of mold M M and then uniting them to the vessel in the saine mold during the continu ous process of jiggering the saine, substao tially as specified.
